Each of my printers yields me an average of 10.95$ per hour.
it might not seem much in a world of crypto millionaires, but assuming they run 20 hours per day,
that’s 6’570$ a month,
per printer.
Now, don’t rush into thinking this is easy money, you just press a button and you are done.
you need a good product, good marketing, even if you product is well thought, it might not be designed for 3printing.
even when printing you need to work:
changing filament, storing it properly, heck even buy the best filament you can for the best price you can is proper work when you buy loads of filament, changing nozzles, packaging your products.
I experienced all this on my skin, with my online shop, also on etsy, through influencers, paid advertising and 5/5 stars reviews.
